APPARATUS 'FOR liflrsl.

To all @alom t vnf/.y concern.:

Be it known that 1.7 ARTHUR Cr. lli-mori, a citizen ot the United States, residing` at Duluth. in the county of et. Louis and State of Minnesota, have invented certain new and useful lmprovements in Apparatus 'for Making' Concrete Bricks, o'l which the following is a specification.

This invention relates to a new and iniproved means and method Jfor making brick, and more particularly for making` brick from concrete or similar material.

Concrete or material of like nature must be handled differently from plastic material such as clay, in the making of bricks. It is impractical to make concrete bricks by any continuous process machine of a type such as those used in extruding Vclay in brick making'. The concrete must be supported until at least the initial set has taken place and this necessity for support involves the provision ot large numbers otmolds where concrete brick construction is undertaken on a large scale. rThis is due to the :tact that the molds must be occupied by each brick for a considerable period ot time. rlhis requirement for a large number ot molds involves very considerable expenditure 'for plant and also requires a large space for oneration, and relatively high labor costs in concrete brick making as now `generally practiced.

It is an object of the present invention to provide a new and improved means and apparatus for forming concrete brick.

ltis a further object to provide molds which are compact in form and so adapted for placing` that pouring of the concrete may be accomplished with a minimum. amount of labor.

lt is an additional object to pr vide molds which are subdivided into easily handled sections and which are formed in such manner that the brick may be readily removed 'from the mold without danger of injury to the brick.

Other and 'further objects will appear as the description proceeds.

Broadly, my invention comprises the tormation of a wooden decking or similar plane surface and the attachment to that surface of vert-ical septums, the septums being; adapted to receive rows ot bricksbetween successive pairs. rlhere are further provided pallets ttinnj between the spaced septums, the pallets being provided with n Specification of Letters Yatent.

transverse septuins properly spaced to form bricks olf the required size. These pallets are freely removable from between the fixed septums attached to the decking and are made of such length as to be readily handled.

I have illustrated a preferredembodiment of my invention in the accompanying dr' wing, in which- Figure l is a plan View showing'A my brick- Y forming mold construction in assembled relation;y v

n Figure 2 is a longitudinal section oii Figure l;

Figure 3 is a transverse section on line 3*3 of FigureA l; o

Figure 4.- is a side view of a pallet with bricks therein; A

Figure 5 is a top view of Figure l; and Figure 6 is a view of a toolused in handling pallets. j n

Referringv to the dr wing, the decking` 7 is provided with avertically ext-endingr side member 8. Running' parallel to this side member are the equally spaced longitudinal scptums 9. As best shown in Figure 3. these septums 9 are preferably formed of flat pieces oit metal and have a port-ion 9 in engagement with the decking and extending'. the full width between adjacent septuins.

itting;f between adjacent pairsv of septums are the pallets lO best shown in Figures l .and These pallets consist oli' flatwooden strips ll slightly less in width than the distance between adjacent septums 9. The pallets are made ol convenient length. those shown beine; sii; bricks lone'. rit either end the pallets are provided with metal handling clips l2, these clips extending under the pallet at l?) and having' sloping portions l-l the ends of the pallet which itacilitate tilting' the pallets in reinoving` them. The upper ends oit the clips l2 curved at 15 and are provided with slots i6. The slots 16 are adapted to receive the bar 17 on the tool 18 shown in Figure 6. rhe upper tace ci the wooden pallet member l1 carries the sheet metal facing' 19 which is formed with upwardly extending reversely bent portions 20, these portions '20 dening the limits et the bricks.

ln the use ot my apparatus7 the pallets are placed between the septurns until the desired area oit the mold deckis covered, T he brick-terminea mix is then poured upon the deck and is evenly distributed by means i facia mix. transverse portions Vcit the pallets may be of a luteor similar tool. The material is `then struck oli' smoothly7 even with the up per surface of the septuins 9 and thetransverse portions 20. y lll/'hen the initial set has taken place,` the pallets are removed. by inserting tools lSat either end and may then be carried by hander tracked to the desired location. where by inverting" the pallet the green bricks easily drop 'from the pallet and may be stored andv cured `until ready 'for use.

An important feature off my invention lies in the ease Withwhich a spe al colored face may be formednpon thebru thematerial has been striick' oil inthe 'forms or molds, the entire" srlr'lace may be easily washed with colored greater with a thin lf desired the septuins and made slightly lower than the desired brick size, and after "the body material has been struck oli' and leveled by means or the sepn turns, an additional thin layer of a 'acia inizi may be smoothed on with a strikeboard or trowel.

My apparat-Lis is adipted tonioldbricks in a small area with a minimum oit labor cost. The material2 as stated, may be dumped in large masses andwsmoothed ont to form a large number of bricks at a `single striking'pl operation. `The pallets l'rorn the pallets when they are removed fs. y After adapted to :Form `the end ilaccs oil brick, s:

are` easily handled and tbe `bricks readily drop` iframes charge oit the brirksis aided byy the slight flexibility ork resilience of the pallets, which may besligbtly bent or 'flexed in disc/har@ ingr the bricks. `I claim: l. Apparatus lor mak ig concrete brick ory the like, comprising a molding deck, spaced parallel septums extending; vertically from the deck', removable pallets .tted between the scptnms, said pallets carrying members adapted to lorm the lower and end :faces of the bricks, and beingprovided with ineanswhereby they may be vertically removed from between the septnn'is the body portions of the pallets being' adapted to'be liexed to facilitate removal of the bricks from the pallets. y l f Y 2.
